From the Rules: "In the Hot Wheels Trading Card Game (TCG), each car is assigned a number for each of 3 Attributes: Speed, Design, and Utility. Players compete using these numbers. When it is your turn, you will select a card from your hand with which you will challenge your opponent. The highest Attribute number on that card is automatically the Attribute players compete with and the highest number wins that Challenge Match." Game play is similar to Top Trumps and its many variations and offspring (e.g., NBA Adrenalyn XL, NFL Adrenalyn XL,Puck Attax, Match Attax, Slam Attax, Topps Attax, etc.). Cards from the Hot Wheels Trading Card Game are sold together with cards from the FunTracks Card Game in Hot Wheels Trading Card Fun Packs.
